On your family trip, you used 9 gallons of gas. If the odometer readings before and after your trip were 74,233 and 74,545, respectively, how many miles per gallon did you average? Round your answer to the nearest whole number.

Respuesta :

Find the number of miles driven by subtracting the odometer readings:

74545 - 74233 = 312 miles driven.

Divide miles driven by gallons of gas used:

312 / 9 = 34.66 = 35 miles per gallon.
